An al-Qaeda-affiliated opposition group has allegedly executed a teenage boy in Syria in front of his family, the Syrian Observatory for Human Rights reports. The boy was shot by the group for supposedly blaspheming.

15-year-old Mohammad Qataa was taken hostage by the extremist
group and was then summarily executed in the northern city of
Aleppo on Sunday night. Pro-opposition group the Syrian
Observatory for Human Rights (SOHR) released a photo of the boy
with bullet wounds in both his face and neck.

The SOHR said witnesses claim Qataa got into an argument at a
coffee stand where he worked in the Sh’ar neighborhood of Aleppo.
He was overheard saying: "Even if the Prophet Mohammad comes
down (from heaven), I will not become a believer."

The Syrian Observatory for Human Rights is a London-based
monitoring group founded in 2006. The group lists its goals
as “observing the Human Rights situation in Syria,
documenting and criticizing all HR violations, filing reports
and spreading it across a broad HR and Media range” on
its official website. The Observatory relies on a broad
network of activists, doctors and lawyers in Syria for its
reports. The group says it is “not linked to any political
body,” though it openly supports the Syrian opposition
and has the opposition flag on its logo.

His words caught the attention of members of the Islamic State of
Iraq and Syria who kidnapped Qatta. They then brought him back to
the stall late on Sunday night with whiplash marks on his body.

According to the report published by the SOHR, one of the members
of the group addressed the crowd and said: “Generous citizens
of Aleppo, disbelieving in God is polytheism and cursing the
prophet is polytheism. Whoever curses even once will be punished
like this.”

"He then fired two bullets from an automatic rifle in view of
the crowd and in front of the boy's mother and father, and got
into a car and left," the report said. It added that the SOHR
demands the killers be brought to justice. Qatta’s mother
allegedly pleaded with the killers, whose accented Arabic
suggested they were not from Syria.

The group expressed concern that the Sharia court of Aleppo had
done nothing to stop the execution of the 15-year-old.

"The Observatory cannot ignore these crimes, which only serve
the enemies of the revolution and the enemies of humanity,"
said the group's leader Rami Abdulrahman. The Observatory also
released a photo of the boy participating in pro-democracy
protests in Aleppo.

There have been a number of reports of opposition brutality in
Syria in recent months. A video disseminated over the internet in
May, purported to show an opposition member taking a bite out of
a soldier’s heart, and drew widespread condemnation from the
international community.

Abu Sakkar, the leader of a group called the Independent Omar
al-Farouq Brigade, an offshoot of the Free Syrian Army, says in
the video "I swear to God we will eat your hearts and your
livers, you soldiers of Bashar the dog". Sakkar expressed no
remorse for the “eye-for-an-eye” attack and pledged to carry out
more such acts.

Currently the international community is pushing to bring both
the opposition and the Assad government to the bargaining table
to end the two-year conflict. There is disagreement as to what
should be done with President Bashar Assad. Russia believes the
President should have a role in the solution to the conflict,
while the Syrian opposition and their allies are calling for his
immediate removal.
